  4. Traces of mould, algae or fungi must be removed with a stiff brush or scraper
  5. Areas that have been affected by mould, algae or fungi should be treated with Ronseal Garden Cleaner
  6. Fill in any gaps or imperfections in the wood with Ronseal High Performance Wood Filler or Ronseal Multi Purpose Wood Filler

Always do a small test area before beginning any project to assess compatibility and suitability. Follow the manufacturer's instructions on the tin at all times.

Excellent product which absorbs into wood by Jackie Pomfret

Soaks in to wood well and looks good by Richard Foster

I cant' tell you how good a preservative it is for another few years but it goes in to the wood well and gives it a natural looking colour enhancement without looking painted. My feeling is that it should last well because it soaks in properly rather than sitting on the surface. It's very high in VOCs and you can smell it a lot whilst it dries.

Does what it says on the tin by Stephen N

This is a product that preserves the wood on your fence, shed and summerhouse. Good colour but needs a couple of coats the first year of application to get good protection. Have tried all the pastel colours but if you live in a tough climate where it rains a lot, stick with a proper preservative like this one. I won't buy anything else now.

Application is easy and enhances the natural look of wood products by Mick Rodgers

Quick application with no skill required. The overall finish is attractive and long lasting. Tins can be sealed and product used at a later date if required. Finished colour match is true to product description. Can't go wrong really.

Great stuff, does the job by Charles

It's great to find a supplier of this product. A lot of the so called "preservers" today are basically coloured water with a bit of biocide in. Not this - good old fashioned preserver soaks into the wood to keep it good for years. Has. Having said that, you do need to be carefull of the environment - don't lwt it get onto plants or into water courses.
